Molecular Interaction between Andrographolide and Glutathione Follows Second Order Kinetics

Fat digestibility in Equus caballus follows increasing first-order kinetics.

The digestibility of ether extract varies greatly from forages to grains and further to added fats consisting mainly of triglycerides. This variation has been attributed to two main factors, the presence of nonhydrolyzable substances in the ether extract, especially in leafy foods, and the dilution of endogenous fecal fat. A compilation of results from 188 equine digestion balance observations ...

Global motion perception: No interaction between the first- and second-order motion pathways

The experiments reported here address the issue of whether the pathways which extract motion from first-order and second-order spatial patterns remain separate or whether they combine at some higher level in the motion system to form a single pathway. The question is addressed by investigating the interaction of first-order and second-order stimuli in the processing of a global-motion stimulus ...

Molecular Dynamics and Molecular Docking Studies on the Interaction between Four Tetrahydroxy Derivatives of Polyphenyls and Beta Amyloid

Interactions of 3,3',4,4'-tetrahydroxybiphenyl (BPT) and three isomeric 3,3",4,4"-tetrahydroxyterphenyls (OTT, MTT, PTT) with Alzheimer’s amyloid-β peptide (Aβ) were studied by molecular dynamics simulation and molecular docking. Structural parameters such as Root-mean-square derivations (RMSD), radial distribution function (RDF), helix percentage and other physical parameters were obtained. Th...

HR* Graph Conditions Between Counting Monadic Second-Order and Second-Order Graph Formulas

Graph conditions are a means to express structural properties for graph transformation systems and graph programs in a large variety of application areas. With HR∗ graph conditions, non-local graph properties like “there exists a path of arbitrary length” or “the graph is circle-free” can be expressed. We show, by induction over the structure of formulas and conditions, that (1) any node-counti...
